Title:Advance Timing an EngineProblem:A street rod owner says that when the timing was advanced on the street rod engine, the engine ran better. If this is correct, should all engines be advanced timed so they run better?Solution: Today’s modern engines have a set timing depending on the type of ignition system that is used. Computerized ignition systems use a computer to advance the timing according to the load, speed, and other variables. However, street rod enthusiast often use older engines. Back in the 1970’s and early 1980’s the timing of engines was actually retarded at the factory to produce less pollution when the street rod is idling. The photo to the left shows the timing mark and gauge used on these engines. Some of these engines ran better when the timing was advanced. If you do advance the timing, make sure the engine doesn't start to have preignition. Always check the plugs for overheating if you suspect preignition. The best advice is to always follow the manufacturer’s recommendations when timing an engine.
